概括

一个新的与热致死相关的基因评分 (PYR_score) 能够有效预测肺腺癌的预后. 通过增加HMGB1,Treg细胞和MDSCs来影响瘤免疫力,这表明IL-8抑制可能会增强免疫疗法.

科学领域:

在瘤学瘤学.
免疫学免疫学免疫学
细胞生物学细胞生物学

背景情况:

人们越来越多地认识到热,特别是GSDME介导的热,但其在肺腺癌 (LUAD) 预后和免疫微环境中的作用尚不清楚.
了解热的影响对于开发有效的LUAD治疗至关重要.

研究的目的:

开发一个与热症相关的预后模型,用于LUAD.
为了研究GSDME介导的烧在塑造LUAD瘤免疫微环境中的作用.
探索潜在的治疗策略,以杀性死途径为目标.

主要方法:

机器学习被用来构建基于灭相关基因的预后模型.
通过使用CHX和TNF-α,在LUAD细胞中诱导了GSDME介导的热.
HMGB1水平通过ELISA测量了细胞超位和患者血清中的HMGB1.
在体内研究中,参与了用各种抑制剂和免疫疗法治疗的易斯肺癌 (LLC) 鼠标模型.

主要成果:

开发的PYR_score模型准确地预测了数据集中的LUAD预后,较高的得分与较差的生存率相关.
通过GSDME介导的烧增加了HMGB1的释放,这与LUAD患者免疫检查点抑制剂的疗效降低有关.
HMGB1促进了Treg细胞的增殖和IL-8的分泌.
抑制Caspase-3和IL-8减缓了小鼠的瘤生长,而IL-8抑制剂可能会增强抗PD-1治疗的有效性.

结论:

PYR_score作为LUAD的可靠预后标志物.
通过HMGB1,Treg细胞和MDSCs,GSDME介导的热致癌有助于免疫抑制瘤微环境.
向IL-8可以通过调节Tregs和MDSCs来克服免疫治疗的耐药性,这需要进一步的临床研究.

关键词:

在GSDME中,GSDME是GSDME.这就是HMGB1的特点.卢阿德 (Luad) 的意思是说.卡斯帕斯-3酶是什么意思机器学习是机器学习.热灭症是什么?

The Tumor Microenvironment

The Tumor Microenvironment

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Tumor Immunotherapy

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
